摘要: The home range of stoats (Mustela erminea) was determined as part a programme to protect Okarito brown kiwi chicks (Apteryx australis) ‘Okarito’, from predation. Twenty-seven were fitted with radio-transmitters and tracked in two podocarp (Podocarpaceae) forests, south Westland, New Zealand, July 1997 May 1998. Home-range area for 19 animals by minimum convex polygons restricted-edge polygons, core areas hierarchical cluster analysis. mean ranges males across all seasons calculated polygon (210 28 ha ( s.e.)) (176 29 ha) significantly larger than those females (89 14 82 12 ha). during the breeding season (256 38 pooled non-breeding (149 16 ha), whereas that not different. different when estimated either method. Overlap observed within between sexes seasons, greatest proportion overlap being male–female. spring summer is used guide spacing control stations.
